In this article, I explore the relationship between the supersession thesis and the rights of future people. In particular, I show that changes in circumstances might supersede future people’s rights. I argue that appropriating resources that belong to future people does not necessarily result in a duty to return the resources in full. I explore how these findings are relevant for climate change justice. Assuming future generations of developing countries originally had a right to use a certain amount of the (...) carbon budget, changing circumstances could result in rights-supersession. Consequently, members of future generations of industrialized countries may be allowed to use part of the share of the carbon budget belonging to developing countries. (shrink)
